Steps to Calculate GCD of 485, 705, 840, 971 using LCM Formula

Given numbers are 485, 705, 840, 971

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(485, 705) = 68385

GCD(485, 705) = ( 485 x 705 ) / 68385

= 485 / 705

= 485


Step2:

LCM(5, 840) = 840

GCD(5, 840) = ( 5 x 840 ) / 840

= 5 / 840

= 5


Step3:

LCM(5, 971) = 4855

GCD(5, 971) = ( 5 x 971 ) / 4855

= 5 / 971

= 5


So, Greatest Common Divisor of 485, 705, 840, 971 is 1
